POLISH-ROD HOLDER.

SPECIFICATION forming part of Letters Patent No. 769,905, datedSeptember 13, 1904.

Application filed November 19, 1903. Serial No. 181,886. (No model.)

To a whom it may concern.-

Be it known that I, SOLOMON E. J EUTTER, a citizen of the United States,residing at Derrick City, in the county of McKean and State ofPennsylvania, have invented a new and useful Polish-Rod Holder, of whichthe following is a specification.

This invention relates to polishrod clamps; and it has for its object toprovide an eificient and easily-manipulated clamp which can be readilyapplied to a polish-rod and rest upon the surrounding pipe end, wherebythe rod will be supported during the process of cleaning the well.

The advantages of this invention, as well as the novel details ofconstruction, will be specifically described hereinafter,reference beinghad to the accompanying drawings, illustrating the preferred embodimentof this invention, and in which- Figure 1 is a top plan view of theclamp applied, and Fig. 2 is a side elevation of the clamp applied.

In the'preferred form of my invention as illustrated in the drawings thedevice is illustrated as comprising two members, one of whichconstitutes the main or supporting part of the clamp and comprises twoparallel arms 1 and 2, terminally connected by a cross-bar 3, so that anintervening space 4: is provided between the arms and serving as a guidefor the movable jaw carried by the arms. At the connected ends of thearms 1 and 2 the space 4 is restricted to provide a seat 5 forfrictional engagement with the rod 6, which may be clamped therein bymeans of the clampingjaw 7. This jaw 7 is conveniently illustrated ascomprising a swinging block having oppositely-disposed trunnions orjournals 8 and 9, which are slidably mounted in the slots 10 in thehook-shaped terminals 11 of the arms 1 and 2.

12 and 12 are adjustable screws which have a longitudinal movement inthe arms 1 and 2, so as to bear against the journals of theclamping-jaw, and thereby provide movable fulcrums therefor, the ends 14acting as the fulcrums for said journals.

It will be obvious that in attaching the clamp the movable jaw may beeasily removed out of engagement with the arms, and the clamp can thenbe slipped onto the rod, after which the movable jaw will again beproperly connected to the clamp. The screws 12 and 12 will be properlyadjusted so that the thrust thereof will properly move the jaw inposition to cause the weight of the rod 6 to produce a binding effectupon the movable jaw, which will force the rod in rigid engagement withthe clamp, so that all liability of the rod slipping will be avoided. Asthe clamp will rest upon some suitable support such, for instance as apipe end-the rod will be properly held in position.

If it is desired to adjust the clamp longitudinally of the rod, this canbe accomplished by lifting the movable jaw, permittinga free movement ofthe clamp. It will also be noted that various sizes of rods can beprovided for by adjusting the movable jaw through the medium of thescrews 12 and 12, which can be manipulated by grasping the wings of thebolts or by employing a wrench.

What I claim, and desire to secure by Letters Patent, is

1. A drill-rod clamp, having parallel arms and a cross-bar connectingthem with an intervening space, the end of which is restricted adjacentto the bar, and a swinging jaw carried by the arms and having a slidingand swinging movement.

2. A drill-rod clamp, having parallel arms connected at one end with arestricted space between the ends of the arms and a swinging jaw carriedby the arms and movable toward the restricted space.

3. A drill-rod clamp, comprising two parallel terminally-connected arms,with a restricted rod-seat therebetween, and a movable rod-clamping jawcarried by the arms.

4:. A drill-rod clamp, comprising two parallel terminally-connectedarms,having hookshaped free ends, and a swinging jaw engaging the freeends of the arms relative to the restricted space.

5. A drill-rod clamp comprising two parallel terminally-connected armshaving hookshaped free ends, a swinging jaw having trun- 2 resets nionsextending from opposite sides thereof, my own I have hereto afiixed mysignature in said aw being mounted between said arms the presence of twoWitnesses.

with the trunnions thereof disposed in said 1 hook-shaped ends, andmeans for regulating SOLOMON JEUTTLR 5 the position of said trunnions insaid hook- Witnesses:

Intestimony that I claim the foregoing as J OHN JACKSON, Jr.
